CHARLES F. SPENCER, OF ROCHESTER, NEW YORK, ASSIGNOR TO ADAM ZIMMER AND HENRY S. BALLOU, OF SAME PLACE.

DROP-LIGHT FIXTURE.

SPECIFICATION forming part of Letters Patent No. 237,211, dated February 1, 1881. Application filed November 8, 1880. (No model.)

To all whom it may concern Be it known that 1, CHARLES F. SPENCER, of Rochester, Monroe county, New York,

have invented a certain new and useful Improvement in Drop-Light Fixtures; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure I is a side elevation of the fixture. Fig. 2 is a cross-section on an enlarged scale. Fig. 3 is a view similar to Fig. 2, but showing a different form of the hanger.

My improvement relates to drop-light fixr5 tures for lamps; and it consists in the con struction and arrangement hereinafter described, whereby great simplicity and cheapness are attained.

In the drawings, A represents the hanger or pendant, which is suspended from the ceiling in the usual manner. Near the bottom it has loops or bearings b b, through which pass right-angled or curved fixtures B B, which are secured at any adjustment by means of 2 5 set-screws c c, which pass through the ends of the hearings and clamp against the fixtures. The hanger may be round, square, or

of any desired form in cross-section, and may be ornamented in any desired manner.

The fixtures B B consist each of a horizontal arm, at, which supports the lamp C, and a vertical standard, f, which runs up through the loop or hearing and is secured by the setscrew, as before described. These fixtures 3 5 may also be ornamented in any desired manner, and may have, in the angle between the horizontal and vertical arms, a flange, g, which serves both as an ornament and a brace or strengthener. The vertical arms ff are each 0 made tapering or wedge-shaped, as shown in Fig. 1, the widest end being at the top. The taper is gradual from top to bottom.

The fixtures above described can all be made of cast-iron, and are therefore very cheap; or, if desired, the hanger can be made of tubing 5 and the fixtures of cast-iron.

Another feature consists in the tapering or wed gin g form of the vertical arms of the hang.- ing fixtures. By this device two advantages are secured first, if by accident the fixture 0 supporting the lamp should be dropped, it would gradually tighten against the set-screw, thereby preventing the fixture from running down its whole length and preventing shock; second, if the setscrew, when turned up, should fail to hold the fixture fast, the latter would work down and be self-tightenin g, thereby holding it against rattling or, loose movement.

Instead of set-screws c c, eccentrics, cams, or similar devices may be used to hold the fixtures.

I do not claim, broadly, lamps having a vertical adjustment separate and independent from each other; but

I claim 1. A droplight fixture for lamps, consisting of the single central hanger, A, provided with loops b b at its lower end, and the lamp-fix,- tures B B, provided with vertical standards ff, resting in the loops and secured by set- 7o screws 0 c, as shown and described, and for the purpose specified.

2. In a drop-light fixture, the combination of the hanger A, provided with the loops b b, the fixtures B B, provided with tapering or wedge-shaped vertical standards f f, resting in the loops, and set-screws c a, clamping against the tapering standards, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

CHAS. F. SPENCER.
